oh, apparently it's not possible to portably check for string-to-float conversion errors in standard c
Summary
The article investigates how C's math_errhandling interacts with string-to-float conversions (strtod and friends), highlighting differences between standard C, POSIX, and libc implementations (glibc vs musl). It provides a portable pattern to detect overflow/underflow and discusses the inconsistencies in man pages and standards. It emphasizes portability challenges when testing for errors in string-to-float conversions.
